The transmigration that happened to others happened to me, too. I'm pretty sure I'm now a supporting character... but exactly which novel is this? When I opened my eyes, I was a widow with stepdaughters my own age, and not only that—I turned into a black swan every night due to a dark curse! Holding back my tears, I decided to take charge of my fate... wait, why should I? Why so serious?

A duchess during the day, a queen of the lake during the night—I have the best luck to be able to leisurely float around! Life should be lived unplanned! When I had just about decided to live my life like this, a white baby swan, one that was not in my no-plan life plan, came to me. "Mommy, are you really my mommy?"

What, you were a person? And even the youngest sibling of the tyrant emperor? "I'm not your mother! Can't you tell by the different colors of our feathers?" I'm a black swan, you're a white swan! But why is she so crazy cute. Can our mother-daughter love endure the obsession and persecution of this child's seven brothers, including the tyrant emperors?
